我试图在 mod_rewrite 中模拟 else

如何解决我试图在 mod_rewrite 中模拟 else

我有这个代码：

RewriteEngine On

# Delete .PHP extension
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.PHP -f
RewriteRule ^([^.]+)$ $1.PHP [L]

# If file does not exist redirect to error.PHP
RewriteCond %{REQUEST_FILENAME}.PHP !-f
RewriteRule ^(.*)$ error.PHP [L]

# Friendly URL
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.PHP -f
RewriteRule ^user/(.*)$ user.PHP?ID=$1 [L] 

问题：第二条语句本身有效，但是当我添加第一条语句时，第二条语句总是将我重定向到 error.PHP。

可能的解决方案：我想过做这样的事情：

if(RewriteCond %{REQUEST_FILENAME}.PHP !-f)
    RewriteRule ^(.*)$ error.PHP [L]
else
    RewriteRule ^user/(.*)$ user.PHP?ID=$1 [L] 

我已经有一段时间试图自己弄清楚如何让它工作，但我不能。 A 将不胜感激。

解决方法

像这样：

Options -MultiViews
RewriteEngine On

# Friendly URL for user/...
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^user/(.*)$ user.php?ID=$1 [L,QSA,NC] 

# Add .php extension internally
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{DOCUMENT_ROOT}/$1.php -f
RewriteRule ^([^.]+?)/?$ $1.php [L]

# If there is no rewrite and 
# files/directory don't exist then forward to error.php
RewriteCond %{ENV:REDIRECT_STATUS} ""
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . error.php [L]
